Step by Step Guide to Building a NeverBounce API Integration in Python

Introduction

Hey there, fellow Python enthusiast! Ready to supercharge your email validation game? Let's dive into integrating NeverBounce's powerful API using their handy Python SDK. Trust me, it's easier than you might think!

Prerequisites

Before we jump in, make sure you've got:

• A Python environment (3.6+ recommended)
• A NeverBounce account with an API key (don't have one? Grab it here)

Installation

First things first, let's get that SDK installed:

pip install neverbounce-sdk

Easy peasy, right?

Setting up the NeverBounce client

Now, let's import the package and set up our client:

from neverbounce_sdk import NeverBounceClient

api_key = 'your_api_key_here'
client = NeverBounceClient(api_key=api_key)

Basic API operations

Single email verification

Verifying a single email is a breeze:

result = client.single_check('[email protected]')
print(result['result'])

Bulk email verification

Got a bunch of emails? No sweat:

job = client.jobs_create(['[email protected]', '[email protected]'])

Job status checking

Keep tabs on your bulk job:

status = client.jobs_status(job['job_id'])

Handling API responses

NeverBounce uses result codes to tell you what's what. Here's a quick rundown:

• 0: Valid
• 1: Invalid
• 2: Disposable
• 3: Catchall
• 4: Unknown

Always wrap your API calls in try-except blocks to catch any hiccups:

try:
    result = client.single_check('[email protected]')
except NeverBounceAPIException as e:
    print(f"Oops! Something went wrong: {e}")

Advanced features

Webhook integration

Want real-time updates? Set up a webhook:

client.jobs_create(emails, callback_url='https://your-webhook-url.com')

Account information retrieval

Curious about your account stats? Here you go:

info = client.account_info()
print(f"Credits remaining: {info['credits_info']['free_credits_remaining']}")

Best practices

• Mind the rate limits! NeverBounce is pretty generous, but don't go crazy.
• Cache your results. No need to verify the same email twice, right?

Example use case

Let's put it all together with a quick mailing list cleanup script:

emails = ['[email protected]', '[email protected]', '[email protected]']
valid_emails = []

for email in emails:
    result = client.single_check(email)
    if result['result'] == 0:  # Valid
        valid_emails.append(email)

print(f"Clean list: {valid_emails}")

Conclusion

And there you have it! You're now armed and ready to integrate NeverBounce into your Python projects. Remember, clean email lists mean better deliverability and happier users. So go forth and validate those emails like a pro!
